Guys, are you in love with your car??
"Harold George Radar" did not invent RADAR. RADAR is an acronym not a name.No single person or country has entire credit for it. Many people were involved in taking RADAR from a concept to a working system.
Robert Watt's British patent is the best well known, giving the popular idea that the British "invented" it.
I believe the British invented the Radar.

Radar was developed by several countries in the mid-late 1930s. The German forces used several systems in WW2 including "Freya" which used arrays of multiple dipoles at VHF and "Wotan" which used parabolic dishes at high VHF or low UHF. Professor Hidegetsu Yagi researched radar for Japan at the same time. In the United Kingdom, the main developer was Robert Watson-Watt.Why do cars have plate numbers?
British radar was better than German though as they used a better system to interpret the results. In addition amateur (ham) radio had been banned in Germany since the Nazis came to power so there were few Germans with general radio experience. The German sets were very well made but simple and fairly low performance so that they could be repaired on site by almost totally unskilled people. By contrast British sets had higher performance but were a little less reliable, and needed people with a bit of training and experience to maintain them.

The kicker though was the invention of the improved cavity magnetron tube in England by physicists Randall and Boot in 1940. This was capable of generating high power at wavelengths of around 10cm without significant drift in operating frequency. The shorter wavelength gave British radar better resolution than the longer wavelengths used by most other countries. When it was sent to the USA, President Roosevelt called it one of the most valuable cargoes to have been sent from the UK to the USA.
.well, Maybe a $.16 difference.that's what the 'Duh' is all about...they've run us us nuts HuH?
The cavity magnetron is still used in microwave ovens.
